^^^ I believe this is the answer. I've always got 2 years out of batteries.. Regardless of brand. I changed to one of those smart charger things that you leave plugged up 24/7 and is supposed to cycle? Or load? Or do something to the battery and this month makes 3 years on My batteries! Way I see it is the charger has paid for itself
